Abstract A full-bridge converter of current-doubling rectifier is composed of input DC voltage, inverting bridge, isolating transformer, and rectifying-filtering circuit, and features that an isolating capacitor is serially connected with primary winding of transformer. Its advantages are zero-voltage switching of switch transistor in wide load range, no loss of duty ratio, no peak voltage of secondary winding, high conversion efficiency and low restriction in leakage inductance of transformer.
